(A little typo :P) Got it, thanks (quite easy, actually). I first thought of long polynomial division, but that's beyond my current knowledge, plus factoring is faster and easier.

Homework Statement For all x>2, \frac{2x²+2x-12}{x-2} simplifies to: 2(x - 2), x + 3, 2(x + 3)(x - 2), x - 2 or 2(x + 3). (Problem taken from http://www.analyzemath.com/practice_tests/act/act_sample_1.html" , question five). Homework Equations None, AFAIK. The Attempt at a...

(It's been a long time since I last looked at this kind of question, so this post may be from moderately to outrageously wrong)First, the electric potential at point r is: V=\frac{k|Q|}{r^2} V Assuming we're working on vaccum, k\approx9\cdot10^9 N\cdot m^2/C^2 and V\approx1125 V. Potential...
